8 Claims.

This invention relates to new and useful imstruct the motor with several diiferent driving.

shafts having difierent characteristics which may 15 be selectively connected with the driven shafts.

For further comprehension of the invention, and of the objects and advantages thereof, ref.- erence will be had. to the following description and accompanying drawing, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawing forming a material part of this construction:--

Fig. 1 is a plan view of a boat with a hand 25 propelled motor constructed according to this invention.

Fig. 2 is a fragmentary sectional view taken on Fig. 4 is a fragmentary perspective view of one of the ends or one of the shafts of the hand propelled motor.

Fig. 5 is an enlarged sectional view taken on 35 the line 55 of Fig. 2.

Fig. 6 is an enlarged sectional view taken on the line 6-6 of Fig. 5. I

The hand propelled motor, according to this invention includes a casing l0 from the opposite 40 sides of which there project the ends of a top shaft II. A bottom shaft I2- is also mounted within the casing and projects from the same ends, except at a lower elevation. Each of the ends of the shafts is equipped with a coupling 45 device of a particular type-one which does not interfere with the swivelling of the entire motor body I0. Specifically, each coupling comprises a tubular portion 13 formed with a square opening 14 to receive the square end of a driven shaft i5. 50 The tubular member I3 is formed from a section [3 which is integral with the motor shaft, and a section l3 which is hingedly connected therewith by a hinge 15. A ring I6 is slidably mounted upon the shaft and is adapted to engage over the 55 Sections B and 13 to hold them relatively closed.

If desired, the ring l6 may be shifted backwards to disengage from the section 13 and this section may then be pivoted open to free the held square end of the driven shaft.

The shaft l l has a beveled gear l8 mounted on it which meshes with a gear I9, in turn meshing with a gear 20 on a shaft 2| extending through the wall of the casing 1!]. The outer end of the shaft 2i is provided with a handle whee1'22 by which the motor may be manually operated.

Theshaft I2 is provided with a pair of pinions 23, 23 which selectively mesh with gears 24, in.

turn meshing with the gear 20 and a gear 25. The gear 25 is fixed on the shaft 26 which extends from the side of the casing ll] opposite the side which they are removably supported upon theshafts. Thus, one or both of the handles may be removed when desired. The pinions 23, are

materially smaller than the gears l8 and conse quently the shaft l 2 will rotate at a greater speed than the shaft l I when the handle wheels 22 are uniformly turned.v j

The casing Ill is supported upon a hollow cylindrical support member 30. An internal cylindrical base member 3| is mounted upon the floor 32 of the boat 33 or any other device. Elements 34 project fromthe base member 3| and engage in bayonet slots 35 formed in the hollow cylindrical member 30 and. by which the support member is supported in different positions. Each of the elements 30 are in the form of screws which are each mounted on a block 31 associated with a screw 38 by which the block may be moved up- 7 wards or downwards relative to the internal cylindricalbase 3!. The screws 34 are provided with heads 34' which are accessible through openings 38 formed in the body it. This body is of hollow construction and has a removable top l0 on which vertical holding posts Ill are mounted for holding same by one hand, while the handle wheel 22 is rotated. c

The boat'33 is provided with the usual rudder 33 and a pair of aligned shafts l5 which have their adjacent ends spaced apart. These shafts extend through suitable bearings 40 mounted in the boat or other vehicle, and are connected with driving elements such as the propellers 4!. In one position of the body Ill the ends of the shaft I! are coupled with the adjacent ends of the shafts l5. If it is desired the coupling jaws I3. may be, swung open by first shifting backwards the rings it. Then the body it) may be turned to disengage the elements 34 from the horizontal portions of the bayonet slots 35 and simultaneously this rotation will cause the tubular portions 13 to completely disengage from the shafts !5. Then the body It] may be shifted along and thereafter turned to re-engage the elements 34 in other of the branches of the bayonet slots. The bayonet slot 35 is provided with a lower branch 35' which is spaced from the upper branch of the bayonet slot at a distance substantially corresponding to the distance between the shafts I i and l 2. In the new position of the body In the shaft H may be coupled with the shafts 15.

Should the shaft I2 be improperly aligned with the shafts l 5 (depending merely upon the particular construction of boat or other device) the screws 34* may be turned toraise or lower the blocks 3'! relative to the internal cylindrical base 3|. This adjustment will compensate for any deficiency in the alignment of the shaft I2 and the shafts I 5. The screws 34 have heads 34 accessible through openings 38 in the housing Hi.

The operation of the device is as follows:-

When the shaft l l is connected with the shafts 13, one or both of the handle wheels 22 may be turned for supplying power and thus rotation to the shaft ll. The shaft I2 will also rotate but will merely be idling. When the casing I0 is shifted to the raised position and the shaft l2 connected with the shafts 15 the motor may be again operated but the mechanical advantage will be varied.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.
